ba260 blew 25amp fuse and funny smell

[glenshaw]

I installed a ba260 as per instructions about 6-8 months ago.
Everything worked and sounded fine.

Now all of a sudden.
When I turned on my radio,
I heard a loud crackle/pop, and then started to smell that funny electronic smell.
Immediatly turned off radio.
Checked and discovered the 25 amp fuse had blown.

Should I bring to a service center or try to replace fuse?

thanks in advance.

P.S. It was cold this morning when it happened ( -13 Celcius )

check all wires and connections

How is your amp grounded??

[glenshaw]

Amp is grounded with a 6" (8 gauge) (same size as power wire)
to a bolt that holds seat onto chassis.

It's really cold up here (Canada) So I'm going to put off rechecking all of the wiring till a warmer day.

But from memory...
all connections were crimped with plastic & metal connectors,
then taped black electrical tape.

All large wiring harnesses(I.E near Head Unit) were also taped with electrical tape.

thanks

was the harness wiring connections made with crimp type connectors??? or just twisted and taped??

Bad ground possibly...did you sand away all paint??

if not...remove that bolt and ground terminal....sand down the spot until it is shiney and you see bare metal...then reconnect the ground

All connections were crimped then taped.

I don't remember if i sanded down.

I'll try that as soon as it gets a bit warmer.
along with verifing all of the connections.

Thanks for your help.

A seat bolt is a bad ground and you need to change it as sonn as possible. Find a flat spot on the floor sand it to bare metal, drill a hole in the floor then nut and bolt the ground there.

Ok, I pull the fuse until I can get it properly grounded.

Question, could there be any un repairable damage done?

I did smell that funny electronic smell...

Thanks

Possible but not likely.

I just removed my ba260 and subwoofer with the same problem, about 2 weeks ago I noticed I didnt have the usual thump to the stereo as I had, I opened the trunk and the sub was not making a sound. I looked under the seat and the amp was not on. I checked the 30 amp fuse at the battery and it was blown. I went too my ground as suggested in this forum and sanded down some more, I replaced the 30 amp fuse and still nothing, I checked the amplifier and the 25amp fuse was blown. I pulled out the 30 amp at the battery and replaced the 25amp fuse, put in the 30 amp fuse at the battery, turned on the radio and the 25 amp fuse in the amplifier blew, repeated this two more times, wasnt having much fun and decided to pull the amp and wiring out, rather be safe than sorry. dont know if its the -35C temperature we had awile ago or not.

is it possible that the amp got so cold (-13 Celcius is f'n cold!) that maybe a little frost formed and as the amp warms up it condenses on the inside and shorts something?
